FUMIGATING ATTACHMENT.

,To @ZL/whom 'it may concern.

"Be it known that l, ERNEST L. B. ZIMMER, a v.citizen of the United States, residing at Minnaxpolis,l in the county of Hennepin land State of Minnesota, havev invented a new and .useful Fumigating Attachment, of which the following is a specification;

M y invention relates toa device adapted to be attached to the outletconduit of a vacuum cleaner or in any other analogous' positions whereby the air blast from the cleaner or any other source'of air shall be i obliged to pass through a body of material moistened with disinfectant or with perfume and forced out at the end of said device either directly into the room or into aA pipe by which it may be conducted to any .y desired place.

v and has an outwardly projectin The object of my invention is to provide a device of the character above which is very simple, which can be attached to the exhaust pipe of a vacuum cleaner and whichca'n be readily opened for the removalof the used disinfecting material and the insertion of new.

In the drawings, Figure 1 is a side elevation of my attachment; Fig. 2 is a longitudinal diametrical section thereof on an enlarged scale; and Fig. 3 is an end view withl the end wall ofthe exterior casing removed.

2 denotes a casing preferably cylindrical and having at the end av cone-shaped portion, 3, having at its apex the inlet pipe 4, the pipe being formed at its extremity with an annular head 5. A coupling 6 'having an inwardly extending annular flange 7, engaging with said head, is attached to the end of the pipe 4, this coupling being screw-threaded on its interior for attachment to the exit pipe 8, of a vacuumcleaner, or toa pipe leading from any other suitable source of `air pressure. The other end of the container 2 is closed by an annular end plate 9, having therein an interior screwthreaded bushing 10. A cap, 11, screws into this bushing 10 nipple 12 screw-threaded on its exterior for engagement with the conducting pipe 13, shown in dotted lines, whereby the air forced through the container may be carried to any desired place.

Mounted interiorly of the container is a cylinder 14, preferably of reticulated or per- .forated material. This is closed at one end 15 by wire mesh or other suitable perforated material and at its yother end has the collar lSpecification of Letters Patent. Application led March 15, 1909. Serial No. 483,569.

16 preferably of sheet metal formed With a screw-threaded neck 17. A cap 18 preferably of pressed4 sheet metal also screwthreaded, is adapted to engage with the neck 17. The face of the cap is perforated as at 19 and the cap is provided wlth a ring, 20, this rin projecting out from the face 'of the cap an being accommodated within the nipple 12. The interior wire mesh cylinder is supported at one end by being attached i circumferentially to the inner face of the cone-shaped portion 3, while the otherv end is supported on radial arms 21 extending outward to the inner face of the casing 2.

The operation of my invention is" evidentl from the above description. Sponofe, cotton or any other like carrier of disinfaction or perfumery is placed within the reticulated cylinder 14 and the cap 18 is screwed home, closing the outer end of `the cylinder 14. The device is then attached by the coupling to the discharge outlet of any 'generator of air pressure, or to the outlet of a vacuum cleaner, as described. rl`he air4 forced through the pipe 4 is obliged to ass through the wire mesh 15 and thereby is brought into contact with the perfumery, medicament, or disinfectant,l supported within the cylinder 14. The air either passes out through the walls of the cylinder into the space between the cylinder 14 and the casing 2, and so out to the front of the casing, or it is forced out through the perforations in the cap closing the cylinder 14. In either case no air can pass out of the outlet opening of the device without having first been brought into intimate contact with the` disinfectant or perfume and becoming charged therewith.

My construction is very simple, has been found entirely effective in use and may be applied to any of the many forms of portable vacuuln cleaners in use today. Its use in this connection is of particular importance as, while the cleaners and dustcollectors associated therewith, vremove dust and like particles from the air passing therethrough, they do not remove germs.-

My device forms practically a germ col,- lector as it might be called in contradistinction to the dust collector, and by its use'the air is not only puried from, dust and material particles of this kind, but also from 'disease germs which might otherwise pass ous bythe fact that they were detached fromy the filaments and dust particles which would otherwise hold them vfrom floating about in the atmosphere.'

A Having thus described my invention, what I claim as new and desire to secure by LettersfPatent, is:

. 153A fumigating attachment for vacuum cleaners, comprising a casing having a con- '--.=ical 'head at.. one end, a `centrallydis}g osed let tube securedk to the head and extending V,ardlyitherefrom, means on the tube for Vvcftilng'ithe-.same with a supply pipe, the p he casing opposite -from'the conical 'hayan'g an `opening, a cap for closing pening provided with a nipple for connection'with an outlet pipe, and a reticulated container arranged within the casing with -Q ,one end disposed in the conical head and `.container being of vsuch transverse dimenf sionthat a surrounding chamber is formed .-3:between the same and casing, said chamber [communicating through the container with tithe space inclosed by the conical head, said fc0nta1ner being adapted to hold a body of i 'material saturated w1th fumigating material Y orthe. like'and permeable to fthe alr passing lthrou vh the casing.

2. i fumigating attachment for vacuum cleanerspcomprisin a cylindrical casing having, a conical hea at one end, an air inlet -device connected with the said head, an

outlet device., connected with the opposite end of the casing, and a cylindrical con- 85 taillerv of openwork material supported cen- "trally in the casing, said containerl being of Vless-diameter than the casing to provide an annular chamber between it and' the latter -and having one end projecting into the 40 conical head with its circumferential edge engaging the internal surface of the latter to prevent thepassa-ge of air from the hollow of the h'ead to the said annular chamber except through the container, one end-of the i' 45 container being supported by its engagement engaging entirely around the same, saidf with thek conical head of the casing, and members extending across the annular chamber from the casing to the other Vend of the container for holding the latter in position, said container being adapted to hold a fumigating or equivalent substance permeable to the air entering the end of the container and passing out -'of the latter to the said' annular chamber.

3. A fumigating attachment for vacuum cleaners comprisin a cylindrical casing having a conical hea at one end, an annular head at the opposite end, an internally threaded ring fitted in the said annular head, a cap screwed into the ring and having a threaded nipple for connection with an outlet pipe, an inlet tube secured to the conical` head andl extending outwardly therefrom, means on the tube for connecting the same with an inlet pipe, a cylindrical container having its'cylindrical Wall and one head formed of reticulated material, a tubular head on the opposite end having a screw bular hea ithread, a (perforated cap screwed on the tuthe said container being of such 'diameter as to provide an annular space 'around the same and the cylindrical portlon of the casing and having the reticulatcd end disposed in the conical head of the casing to coperate therewith to form an inlet chamber separate from the said annular chamber and communicating with thc latter through the container, and supports between the cas- .ing and container at the end thereof opposite from that engaging in the tubular head to support the container in central axial position. l

In testimony, that I claim the foregoing as my own, I have hereto' aiixed my signature in the presence of two Witnesses.
